Thank you Margot for your excellent report on the birds you scouted during your various trips to RBR!





On a 4 day trip to Redwood Beach Resort, including visits to the estuary (adjacent to Padre Ramos) and Cosiguina volcano, late December (27-31) 2010, I identified the following 82 species. I was especially amazed at the number of birds in the small (curvy) river just next to the resort. One morning at 6.15 it was crowded with 6 types of heron (little blue, great blue, green, tricolored and snowy and great egret), two white ibis, a group of about 14 black-necked stilts, a willet, a few blue-winged teals and several smaller waders. On the dead tree above all this was an osprey watching, while a ringed kingfisher flew in, all this accompanied by a concert of flocks of orange-chinned parakeets and great-tailed grackles that were bathing around the corner. Further up the river were many other birds taking their morning bath or drinking from the river, such as painted buntings, a mangrove cuckoo and a northern waterthrush. From the top of Cosiguina we saw a pair of scarlet macaws. Great birding, also on the way to Potosi/Cosiguina! 

I added two particularly interesting species that I did not see this time but that were there during our visit in November 2009: Roseate Spoonbills and the Rufous-browed Peppershrike.  

On a visit in December 2013 I saw several some additional species - including a vermiculated screech-owl that I scared when I got lost trying to find my way back to the hotel through the bushes - bringing the list to 96 species in total. Two Canadian visitors saw a turquoise-browed motmot (Nicaragua?s national bird) and a group of wood storks close to the resort. The day after a much larger group (of about 50) wood storks returned (probably from the nearby wetlands) completely overcrowding the small river. 

Please let Stacy and Mike know if you see any species that are not yet on the list. Happy birding!
